🟦🟥🟨🟩 Custom components

Component description consists of defining meta-information about the component - component name, component type, component properties. Meta-information on component properties in Formengine is called an annotation.

Well, let's describe some existing component from the popular MUI library. As an example, let's take a Button:

Example of a custom component definition

import {Button} from '@mui/material'
import {define, disabled, event, oneOf, string} from '@react-form-builder/core'

// Let's call our component matButton, using the prefix 'mat' to make it easy to understand
// from the name that the component belongs to the MUI library.
//
// Here we call the define function and pass it two parameters - the Button component
// and the unique name of the component type.
export const matButton = define(Button, 'MatButton')
 // component name displayed in the component panel in the designer
 .name('Button')
 // define the component properties that we want to edit in the designer
 .props({
   // button text
   children: string.named('Caption').default('Button'),
   // button color
   color: oneOf('inherit', 'primary', 'secondary', 'success', 'error', 'info', 'warning'),
   // button disable flag
   disabled: disabled,
   // callback fired when the button is clicked.
   onClick: event,
 })
